Police Chief Richard Glavin resigned Friday after police in his hometown of Tyngsborough said they arrested him Thursday night on drunken driving and assault charges.

In a press release, Acting Tyngsborough Police Chief Richard Howe said Glavin was arrested after officers went to a two-car crash around 9:30 p.m. near Chronopoulos Way.

After questioning both drivers, police found "probable cause" to arrest Glavin, 50, whose address in Tyngsborough was not released, Howe said.

Glavin was charged with drunken driving, driving to endanger and assault, said Howe. Police did not offer any more detailed information about any of the charges.

Howe said Glavin was arraigned Friday in Lowell District Court.

No one was hurt in the crash, Howe said. He said the two vehicles are a 2010 Honda Civic and a 2011 Ford Fusion.

Glavin was issued a 2011 Ford Fusion by the town of Sudbury, Town Manager Maureen Valente confirmed Friday night.

"We regret to announce that Police Chief Richard Glavin has resigned from his position with the town effective immediately," Valente wrote in a press release Friday night. "Last evening Chief Glavin was involved in an out of town, off-duty incident which led to this decision.

"Chief Glavin served the community with distinction for over twenty years and we wish him nothing but the best as he deals with whatever personal issues he must address," Valente added. "Unfortunately, the events of last evening necessitate this action."

A woman who answered the telephone at Glavin’s home Friday night said he was not available.

Selectman Vice Chairman Robert C. Haarde said Friday night he was reserving comment until he receives first-hand information from the Tyngsborough Police Department about the arrest.

Glavin was named acting chief in March 2009 following the retirement of former Chief Peter Fadgen. He was sworn in permanently in January 2010. He served for four years with the Billerica Police Department before coming to Sudbury.
